Medicare Cost Report Due Date for 2025: What Providers Need to Know

Enrolled physicians and other medical providers must submit a yearly Medicare Cost Report, a complete financial and statistical account of their activities. The report assists the Centers for Medicare & Medicaid Services (CMS) in calculating reimbursement, assessing facility performance, and checking for compliance. But most important of all to remember about the cost report is the due date.

If you are an administrator, consultant, or provider, you must determine when your Medicare Cost Report is due in 2025. This will prevent penalties, payment delays, and compliance issues.

What Is The Medicare Cost Report?

The Medicare Cost Report is a required filing for all institutional providers who are Medicare-certified, including:

• Hospitals
• Skilled Nursing Facilities (SNFs)
• Home Health Agencies (HHAs)
• Federally Qualified Health Centers (FQHCs)
• Rural Health Clinics (RHCs)

This report provides:

• Total costs of care
• Patient revenues
• Payer mix
• Usage statistics
• Medicare payments and arrangements

Each provider uses the report form appropriate to the type of organization (e.g., Form CMS-2552-10 on hospitals).

When is the Medicare Cost Report due in 2025?

The primary CMS regulation is as follows:

“Five months after the close of the provider’s fiscal year, the Medicare Cost Report is due.”

Your specific due date in 2025 will be determined by when your fiscal year closes for your building. Below are some typical examples:

If your fiscal year is December 31, 2024, you must file your Medicare Cost Report by May 31, 2025.

What If You Miss the Deadline?

Not timely filing your Medicare Cost Report can result in serious problems, including:

• Suspension of Medicare payments: CMS will suspend payments until the report is received.
• Loss of cost-based reimbursement: Particularly for Critical Access Hospitals (CAHs), FQHCs, and RHCs.
• Possible penalties or audits: Especially if delays are often or unreasonable.

CMS values timely filing. You must either:

1. Pay your final cost report by the deadline, or
2. Request and obtain permission for an extension before the deadline.

Can You File for an Extension?

Yes — but it’s not inevitable.

You can request a 30-day extension for a valid reason (e.g., audit delays, staff issues, or a natural disaster). To do so, you must:

1. Request an extension in writing before the deadline.
2. Forward your request to your Medicare Administrative Contractor (MAC).
3. Provide the reports substantiating the necessity for the extension.

The MAC can either grant or deny your request. Could you not take it for granted?

Tips for Meeting the Deadline

Here are some valuable tips that will help you to handle your 2025 Medicare Cost Report:

1. Know Your Fiscal Year

It may be self-evident, but variable financial calendars are the norm in most organizations. Double-check your year-end date in advance so you know your exact deadline.

2. Begin Preparing Early

Start collecting data, cost allocation statements, and supporting papers at least 3 months before the due date.

3. Use E-Filing Tools

CMS requires that all cost reports be submitted online through:

• MCReF (e-Filing for Medicare Cost Reports) portal
• CMS-approved software (for example, HFS or Myers & Stauffer software).

4. Double-Check for Completeness

• Your cost report should be:
• Signed and sealed
• Free of errors

Completely reconciled with financial statements. Otherwise, CMS will reject it as “not filed.”

5. Speak to Your MAC

Call your Medicare Administrative Contractor in advance if you’re unsure about a deadline or need clarification. They can assist you in working out problems before they turn into delays.

What Do You Need to File?

Here’s a convenient checklist of the documents typically found in your cost report package:

• Balance sheet account list
• Adjustments to balance expenses
• Statistical information (for example, FTEs, visits, patient days)
• Medicare agreement terms
• Audited or unaudited financial reports
• Signature and certification page

Ensure you correctly upload your cost report through MCReF and retain a receipt or confirmation for your records.

Who Presents The Report?

Usually, the cost report is done by:

• In accounting or finance departments
• External consultants (particularly for the smaller providers)
• CPA or audit firms specializing in healthcare

Regardless of who is preparing it, the provider’s CEO or CFO has to sign it as accurate.

2025 Key Takeaway

The deadline to file the 2025 Medicare Cost Report hinges on the close date of your fiscal year. For most providers whose financial year closes on December 31, 2024, the filing deadline is May 31, 2025.

Avoid payment delay or penalty risks. Prepare, stay organized, and submit via the CMS MCReF portal promptly.
